Three. Project brief introduction

This project belongs to the cement industry's energy saving, environmental protection and high efficiency grinding technology.

In view of the traditional high energy consumption and high pollution backward cement preparation process, the research focuses on the physical and chemical properties, grinding process, equipment development, system parameter setting, product performance and other aspects of cement grinding raw materials, and develops vertical grinding semi finishing cement technology and complete sets of equipment, through the establishment of vertical mill. + The semi finishing grinding process system composed of ball mill is used to realize different parts of cement grinding, multi-stage powder selection, and finished product mixing, so that the ball mill material has the advantages of fine particle size and homogeneous size, narrow particle gradation range, and remarkably improved grindability. It greatly improves the output of cement grinding system and reduces the energy consumption and cost of cement production. The results can be widely used in the production of new dry process cement at home and abroad, reduce the excessive consumption of limestone resources of cement raw materials, scientifically and rationally utilize industrial waste residue, reduce the pressure of environmental pollution such as carbon dioxide emissions, and reduce the production cost of enterprises.

Through the successful implementation of this project, we have innovating the idea of using the whole external circulation cement vertical mill to carry out the cement semi finish grinding process, providing a new energy-saving and efficient grinding technology and equipment scheme for the cement industry, and developing the supporting technology for this technology. HRM51.4Y , HRM43.4Y , HRM36.3Y And other specifications of all outer circulation vertical mill equipment, has been able to meet the annual production. Eighty ~ Three hundred The matching requirements of 10000 tons cement production line have promoted the technological progress of the cement industry and become one of the most popular technologies in the cement industry in recent years. The key technological innovations of the project are as follows:

(1) developed a semi finishing cement process system for vertical mill and developed it. HRM The series of all external circulation cement vertical mill is used as the core equipment and the ball mill to form a cement combined semi finish grinding process system. The grinding powder is designed to realize the "piecewise grinding, multi-stage selection and mixing of finished products" of different components of cement. The cement product has excellent performance and the comprehensive power consumption of the system is low.

(two) develop HRM The whole external circulation series cement vertical mill adopts thin layer. + The new material bed grinding technology of high pressure grinding roller eliminates the ventilation inside the mill, does not need to spray water in the mill, optimizes the speed adjusting technology of the grinding wheel, develops the device for stabilizing the feed buffer layer and the double adjustable material ring with adjustable height, realizes the stability and continuity of the material layer, reduces the escape of the large particle material, reduces the circulation load, and the system runs stably.

(three) the whole outer circulation cement vertical grinding disc lining board adopts composite surfacing technology. The liner body is first cast and machined after whole, and then cut by blocks, which improves the grinding curve fitting degree of the grinding roller and the millstone and improves the grinding efficiency.

(four) developing on-line testing roller speed and other devices, combined with its own remote intelligent diagnosis technology to improve the grinding system stability.

Four, objective evaluation

Anhui Provincial Institute of science and technology information finds that: " The technical innovation and characteristics of the pre grinding vertical grinding semi finishing cement technology and equipment are introduced in this project: the mill body has no powder selection device. After grinding, all the materials enter the scraper device and discharge through the slag discharge port. ... It has not been reported in the literature that the pre grinding vertical grinding semi finishing cement equipment, such as the mill body no powder selection device, the tire roller and bowl type grinding disc, the high roller grinding device, the double retaining ring structure and the Internet remote monitoring technology. "

Two thousand and seventeen year Twelve month Twenty-six The results of this project were identified by the China Federation of building materials. The conclusion is: "the main technical and economic indicators of the project reach the international advanced level. The successful application of the results is of positive significance for promoting energy saving and emission reduction in China's cement industry, with significant economic and social benefits and broad market prospects. Suggestions: increase efforts to promote results. " Identification number of scientific and technological achievements: building materials identification [2018] The first 005 Number)

Five. Popularization and application, economic and social benefits.

Five ~ 7kWh/t If the cement production capacity is available in the whole country 10% The application of this technology upgrading and upgrading will bring about a new increase in production value for the company. Twenty In the future, users can save more electricity every year. Ten Billion kilowatt hours Electricity per kilowatt hour Zero point four Coal per kilogram is calculated every year. Economize on coal Forty-eight Ten thousand tons, At the same time reduce millions of tons. CO2 discharge In addition, large amounts of desulphurization gypsum, slag and coal gangue can be digested locally every year. It has obvious social benefits in solid waste utilization, energy conservation and emission reduction, green environmental protection and so on.
